dev-perl/App-perlbrew: Cleanup old in relation to bug #614670

All these versions are affected both by '.' in @INC breakages
and unescaped { in installed .pm files ( exposed by tests )

Purging these in favour of a long stable version without { issues
which will be easier to fix.

( Due to the nature of where the failure occurs, its going to be
a substantial amount of effort to simply backport the fix for,
as it affects runtime code, meaning -r1 bumps are necessary for all.

Add to this the nature of the failure involves code fat-packing, and
its all a bit terrible to maintain this ourselves.
